Definitions

  • the present invention relates to a diamond-tipped indenting tool which is used to mark the surface of metal parts.
  • Indenting tools are incorporated within a marking machine and are used to mark parts for identification purposes, or to generate a surface treatment, or a surface condition.
  • the point of the tool will strike the surface of a part and on impact will create a cold-formed indentation or mark. This is often repeated in various locations to produce a pattern. With continued use, the indenting tool point will eventually wear or break.
  • an indenting tool broadly comprises a shank having a tip end and a diamond affixed to the tip end by a braze material, with the diamond forming a tip for the tool.
  • the diamond preferably comprises a high quality single crystal diamond.
  • the braze material preferably comprises a brazing alloy which wets both the diamond and the material forming the shank.
  • an indenting tool 10 in accordance with the present invention has a shank 12 with a tip end 14, a diamond 16 forming the tip of the tool 10, and a braze material 18 for joining the diamond 16 to the tip end 14.
  • the tip end 14 is tapered as shown in FIG. 2.
  • the orientation of the diamond's crystal, as provided in the stereographic projection triangle shown in FIG. 3, is preferably aligned with the shank axis 24.
  • the shank 12 is formed from at least one material selected from the group consisting of stainless steel, hardenable tool steel, a cemented carbide material, and combinations thereof.
  • the shank 12 may also have a head 20 at a second end opposite the tip end 14.
  • the head 20 may be integrally formed with the shank 12 or may be joined to the shank 12 by a welding or brazing material or by a press fitting operation.
  • the shank 12 and the head 20 can vary dimensionally to meet marking requirements and/or to complement the marking machine in which the tool will operate.
  • the head 20 is wider than the shank 12.
  • the head 20 can be made from the same material as or a different material from that forming the shank 12.
  • the brazing material 18 preferably comprises a brazing alloy which wets the diamond 16 and the material forming the shank 12.
  • a suitable brazing material 18 is any suitable silver copper braze material known in the art.
  • the silver copper braze material may contain a minor addition of a reactive element.
  • the diamond 16 is preferably a high quality single crystal diamond.
  • the diamond should be free of defects such as inclusions, porosity, or cracks because such defects can cause significant reductions in tool life. However, minor defects may be present in the loose diamond if they can be removed by grinding once mounted, or if they can be relegated to a position far from the working point 22 of the diamond.
  • the diamond stone size should allow for sufficient length at least greater than the indentation depth when finish ground. Using a larger diamond stone is not detrimental to the operation of the tool 10.
  • the diamond 16 is inspected to determine the intrinsic crystallographic directions. Then the diamond 16 is brazed to the shank tip 14 in a particular orientation as provided in the stereographic projection triangle shown in FIG. 3. For cubic crystal structures such as diamonds, a stereographic projection triangle is a useful tool to graphically display all possible crystal orientations. In FIG. 3, reference common crystal directions are identified at the corners. A very desirable super wear-resistant indenting performance can be achieved by mounting the diamond in the ⁇ 17,12,24> direction shown in FIG. 3 or within 5 degrees from this direction denoted by the dotted line in FIG. 3. Proper positioning of the diamond 16 can be verified using X-ray diffraction techniques in the as-brazed condition or in the finish ground condition. With regard to the brazing of the diamond 16 to the shank 12, a vacuum brazing process is preferred over brazing in air for better wetting of the braze alloy. Any suitable vacuum brazing process known in the art may be used to mount the diamond 16 to the shank 12.
  • the tool point 22 is final ground and/or lapped to a geometry determined by the desired shape of the part indentation.
  • the tool point 22 may be a 90 degree or 120 degree included angle conical and can be used in the as-sharp condition or after a small radius is lapped onto the point 22.
  • the diamond 16 may be a synthetic single crystal diamond. Benefits associated with using a synthetic diamond include elimination of internal defect concerns normally associated with natural diamonds and possibly greater control over the crystal orientation.
  • the tool 10 shown in FIG. 1 may extend 4 inches (10 mm) from an end of the head 20 to the tip of the diamond 16.
  • the shank 12 may have a diameter of one eighth of an inch (3.17 mm).
